Summary
Reclassifies (or changes) the values of the input cells of a raster using an ASCII remap file.
Usage
The input raster must have valid statistics. If the statistics do not exist, they can be created using the Calculate Statistics tool in the Data Management Tools toolbox.
The output raster will always be of integer type. If the output assignment values in the ASCII file are floating-point values, an error message will be returned and the program will halt.
Syntax
ReclassByASCIIFile_3d (in_raster, in_remap_file, out_raster, {missing_values})
Parameter | Explanation | Data Type |
in_raster | The input raster to be reclassified. | Raster Layer |
in_remap_file | ASCII remap file defining the single values or ranges to be reclassified and the values they will become. Allowed extensions for the ASCII remap files are .rmp, .txt, and .asc. | File |
out_raster |
The output reclassified raster. The output will always be of integer type. | Raster Dataset |
missing_values (Optional) | Denotes whether missing values in the reclass file retain their value or get mapped to NoData.
| Boolean |
Code sample
ReclassByASCIIFile example 1 (Python window)
This example uses an ASCII remap file to reclassify the input raster.
import arcpy
from arcpy.sa import *
from arcpy import env
env.workspace = "C:/data"
arcpy.ReclassByASCIIFile_3d("slope","remapslope.rmp","C:/output/recslope")
ReclassByASCIIFile example 2 (stand-alone script)
This example uses an ASCII remap file to reclassify the input raster.
# Name: ReclassByASCIIFile_Ex_02.py
# Description: Reclassifies values of the input raster using an ASCII remap
# file.
# Requirements: 3D Analyst Extension
# Import system modules
import arcpy
from arcpy import env
# Set environment settings
env.workspace = "C:/data"
# Set local variables
inRaster = "slope"
inRemapFile = "remapslope.rmp"
outRaster = "C:/output/recslope"
# Check out the ArcGIS 3D Analyst extension license
arcpy.CheckOutExtension("3D")
# Execute Reclassify
arcpt.ReclassByASCIIFile_3d(inRaster, inRemapFile, outRaster)
